st: 3-level model for crime victimization

Dear Statalisters
I am running a, so far, 2 level model on crime victimization using a survey
of 8 neighborhoods in a large city in Brazil. The firs level is individual
level predictors and the second level is neighborhood level predictors.
Since the survey is not representative of the whole municipality, would I be
able to include a 3rd level with citywide variables to estimate the effect
of policy?
Thanks in advance
